Nothing is too big to fail in crypto world, Terra Luna is a big example that the safety of your money isn't guaranteed even if you invest in top altcoins out there, it's the same risk involve with crypto generally including BTC but BTC is just way safer, I have seen people losing 6 figures to Luna and some Defi projects, first of all try to understand what you are going into, many don't know how risky crypto space is, take risks with what you are ready to throw away.
What's happening to Luna is general something that alway occur in cryptocurrency industry, already no cryptocurrency currently is in the better position right, provided that you have make up your mind of having cryptocurrency in your agenda, the risk most be admitted in all forms knowing that cryptocurrency is not assured in the lines of acceleration and fluctuations, at this State Bitcoin who is the mother of all cryptocurrencies is experiencing dip market, so it's obvious to that currencies that lack potentiality will be in the bad state.
